I used a Craftsman 7″ random orbital buffer for the two polishes.. I think I need a Porter Cable machine and some good foam pads to get some better results. The Craftsman would be fine for applying wax or sealant, but the motor is too weak to do much else really. I used it for the polishes because it’s easier than doing it by hand 🙂

This machine is the one that I want. Seems to be quite popular amongst the enthusiast, and even professional, detailing community.
